RAISED INTERSECTIONS
(See also Raised Crosswalks)
These are raised areas, which cover the entire intersection. They have ramped edges on all approaches and exits and can incorporate textured paving materials on the flat section.
The raised section is usually at sidewalk height or may be slightly below to provide a ridge for the visually disabled pedestrian. They make the entire intersection area a pedestrian oriented zone and are benefit from not impacting parking. They are a moderately expensive measure.
Raised intersections, sometimes called raised junctions, intersection bumps or plateaus.
